Java - .jar libraries methods conflict?

StackOverflow https://stackoverflow.com/questions/17497600

Question

I have one application which needs to have httpclient-4.2.5.jar library to run correctly. I also want to use HtmlUnit library (ver. 2.12). It fails (I think) because of library conflicts (between httpclient-4.2.5.jar and htmlunit-2.12.jar)

Here is output from my log, but I do not understend too much what it says to me because I do not call any of this methods in log...

La solution 2

Well, the only solution which works for me is to downgrade to httpclient 4.2 - http://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient/4.2

Autres conseils

It is all very simple. HtmlUnit makes use of a private method in HttpClient code through refection:

http://sourceforge.net/p/htmlunit/code/8377/tree/trunk/htmlunit/src/main/java/com/gargoylesoftware/htmlunit/HtmlUnitSSLSocketFactory.java#l113

The method in question was removed in version 4.2.4. See HTTPCLIENT-1320

promote the htmlunit version to 2.15 would fix the problem. worked for me

Quickly checked the "org.apache.http.conn.ssl.SSLSocketFactory" class documentation and there's no such "createDefaultSSLContext()" method there.

I had this problem because I wanted to use WebClient in Selenium.

I upgraded Selenium from 2.33.0 to 2.45.0 and WebClient worked fine afterwards.
